I would like to rebarrel my SS Rem 700 ML. The rifle is currently a 54 cal and I want to keep it that way. It will be used to shoot 425+ grain lead conicals as sabots are not legal to hunt with in my home state.
I purchased the rifle used and fired a few sabot loads threw it to see what it would do. The sabot stuff ran sub 2" at 100 yards. When I switched to lead conicals my groups jumped to about 6". I tried at least 4 different bullets with various amounts of Goex FFG and never really bettered that performance. The current barrel has a loose area in the bore. I'm guessing that loose area is the problem.
I have seen several people talk about PacNor as a source for rebarreling, but I don't see a .540" option, and I would really like to keep it a 54. Does anyone know of any suppliers of suitable blanks?
